After a wet winter, deserts that look barren most years can carpet themselves in color. These "superblooms" are short, unpredictable and spectacular.
Why superblooms happen
Desert annuals wait as seeds for the right conditions: well-timed autumn and winter rains, mild temperatures and not too much wind. When it all lines up, millions germinate at once. In dry years there may be almost nothing.
When and where
- Low deserts (Anza-Borrego, Death Valley, the Sonoran Desert in Arizona): late February to April.
- Higher deserts and foothills: April to May.
- Cactus blooms (saguaro, prickly pear, hedgehog): mostly April to June.
Our state bloom calendars for California and Arizona show which species flower each month, based on iNaturalist observations. Park websites and local reports track the current year's bloom.
Light and lenses
- Low side-light at sunrise and sunset shows texture in poppy and lupine fields; midday flattens color.
- Many desert poppies close in the evening, on cloudy days and in wind — mid-morning can be best.
- Wide lens close to the flowers for fields stretching to mountains; telephoto to compress drifts of color.
- Macro for cactus flowers and bees.
Wind
Desert afternoons are windy. Shoot early, use faster shutter speeds, and try intentional blur for impressionistic fields.
Protect the bloom
Superbloom crowds have trampled hillsides badly enough to close areas. Stay on trails, never lie down in the flowers, and don't pick them. A photo of a pristine field is worth more than one of a flattened one.
